* You can configure as many regular expressions as needed to be allowed or denied. Regular expressions to be denied take precedence over configurations to be allowed.

* The allow/deny-configuration and allow/deny-configuration-regexps statements are mutually exclusive and cannot be configured together for a login class. At a given point in time, a login class can include either the allow/deny-configuration statement, or the allow/deny-configuration-regexps statement. If you have existing configurations using the allow/deny-configuration statements, using the same configuration options with the allow/deny-configuration-regexps statements might not produce the same results, as the search and match methods differ in the two forms of these statements.
